BACKGROUND:  Diabetic ketoacidosis and the hyperosmolar hyperglycemic state are the most serious diabetic emergencies. Before the discovery of insulin in 1921 by Banting and Best the diagnosis of type 1 diabetes was fatal ending in diabetic ketoacidosis equivalent to a torturous death. Today, mortality from diabetic ketoacidosis is low at approximately 2 %. But each death from these two acute metabolic complications of diabetes is potentially avoidable by improved patient and healthcare professional education...

Onion ( Allium cepa L.) is widely consumed as food or medicinal plant due to its well-defined health benefits. The antioxidant and antihyperlipidemic effects of onion and its extracts have been reported well. However, very limited information on anti-hyperglycemic effect is available in processed onion extracts. In our previous study, we reported that Amadori rearrangement compounds (ARCs) produced by heat-processing in Korean ginseng can reduce carbohydrate absorption by inhibiting intestinal carbohydrate hydrolyzing enzymes in both in vitro and in vivo animal models...

Hepatic insulin resistance and increased gluconeogenesis are known therapeutic targets of metformin, but the role of hepatic glycogen in the pathogenesis of diabetes is less clear. Mouse model of neuropeptide Y (NPY) overexpression in noradrenergic neurons (OE-NPYD βH ) with a phenotype of late onset obesity, hepatosteatosis, and prediabetes was used to study early changes in glycogen structure and metabolism preceding prediabetes. Furthermore, the effect of the anti-hyperglycemic agent, metformin (300 mg/kg/day/4 weeks in drinking water), was assessed on changes in glycogen metabolism, body weight, fat mass, and glucose tolerance...

We evaluated the hepatic and nonhepatic responses to glucose-responsive insulin (GRI). Eight dogs received GRI or regular human insulin (HI) in random order. A primed, continuous intravenous infusion of [3-3 H]glucose began at -120 min. Basal sampling (-30 to 0 min) was followed by 2 study periods (150 min each), P1 and P2. At 0 min, somatostatin and GRI (36±3 pmol/kg/min) or HI (1.8 pmol/kg/min) were infused IV; basal glucagon was replaced intraportally. Glucose was infused intravenously to clamp plasma glucose at 80 mg/dL (P1) and 240 mg/dL (P2)...

Organotins (OTs) are considered some of the most toxic chemicals introduced into aquatic environments by anthropogenic activities. They are widely used for agricultural and industrial purposes and as antifouling additives on boat hull's paints. Even though the use of OTs was banned in 2008, elevated levels of OTs can still be detected in aquatic environments. OTs' deleterious effects upon wildlife and experimental animals are well documented and include endocrine disruption, immunotoxicity, neurotoxicity, genotoxicity, and metabolic dysfunction...

BACKGROUND: Hyperglycemia is a common adverse event associated with parenteral nutrition (PN); however, there is no consensus on optimal glucose monitoring. Unnecessary point-of-care (POC) blood glucose (BG) testing can result in additional healthcare cost and discomfort to the patient. This study's aim was to determine whether decreasing the frequency of POC glucose testing in patients receiving PN can reduce costs without increasing the frequency of glycemic events. METHODS: This study examined adult, noncritically ill patients who require PN and are managed by a nutrition support team...

Peptides are the largest/most diverse class of molecules used by animals for chemical communication, and with their cognate receptors, are key players in modulating physiological/behavioral control systems, including those involved in adaptation to environmental change. Crustaceans have long served as models for investigating peptidergic control of physiology/behavior, and members of Notostraca, an ancient branchiopod order, have recently been proposed as models for investigating the genetic/physiological underpinnings of ecoresponsiveness; nothing is currently known about the genes/proteins underlying peptidergic signaling in any member of this crustacean taxon...

BACKGROUND: After the introduction of the universal definition of myocardial infarction, the incidence and diagnosis of type 2 myocardial infarction have risen dramatically, yet there are no clear guidelines on clinical management. Diabetic patients are at high risk for developing type 2 myocardial infarction when admitted in a decompensated state and they are also at high risk for future cardiovascular events. METHODS: We performed a retrospective analysis of 1058 patients between 2011 and 2016 admitted with diabetic ketoacidosis or hyperosmolar hyperglycemic state...

Treating hyperglycemia in previously non-diabetic individuals with exogenous insulin immediately after kidney transplantation reduced the odds of developing Posttransplantation Diabetes Mellitus (PTDM) in our previous proof-of-concept clinical trial. We hypothesized that insulin-pump therapy with maximal insulin dosage during the afternoon would improve glycemic control compared to basal insulin and standard-of-care. In a multi-center, randomized, controlled trial testing insulin isophane for PTDM prevention, we added a third study arm applying continuous subcutaneous insulin lispro infusion (CSII) treatment...

RATIONALE: Hyperglycemic hemichorea tends to affect elderly patients with type 2 diabetes, women, and the Asian population. The onset of involuntary movement typically occurs at the hyperglycemic state and subsides at the euglycemic state. In this report, we present an unusual case that developed delayed-onset hemichorea after hyperglycemia correction. PATIENT CONCERNS: A 70-year-old man was admitted to neurology ward with symptoms of subacute dizziness. Hyperglycemia and high level ketone body was incidentally noted...

Hyperglycemia induced oxidative stress inside the cells. Myricitrin, as an antioxidant plant-derived component, may be useful in hyperglycemia. Hence, the aim of this study was conducted to evaluate the antioxidant effects of myricitrin on hyperglycemia-induced oxidative damage in myotubes (C2C12 cells). In this experimental study, mouse myoblast cell line (C2C12) was obtained and divided into five groups: control, hyperglycemia, hyperglycemia + myricitrin 1, 3, and 10 μM. After treatment period for 48 h, cells were collected, homogenized, and centrifuged at 2000 rpm for 10 min...

The urethral muscle of diabetic pregnant rats is affected by long-term mild diabetes and short-term severe diabetes, which plays a crucial role in the pathogenesis of pelvic floor disorders. We hypothesized that muscles outside the pelvis are subject to similar changes. The current study aimed at analyzing the effects of long-term mild and short-term severe diabetes on the structure and ultrastructure of fiber muscles and collagen in rats' rectus abdominis (RA) muscle. Therefore, the RA muscle of virgin, pregnant, long-term mild diabetic, short-term severe diabetic, long-term mild diabetic pregnant and short-term severe diabetic pregnant 3-month-old Wistar rats were collected...

Previous studies by our group on mangiferin demonstrated that it exerts an anti‑hyperglycemic effect through the regulation of cell cycle proteins in 3‑month‑old, partially pancreatectomized (PPx) mice. However, β‑cell proliferation is known to become severely restricted with advanced age. Therefore, it is unknown whether mangiferin is able to reverse the diabetic condition and retain β‑cell regeneration capability in aged mice. In the present study, 12‑month‑old C57BL/6J mice that had undergone PPx were subjected to mangiferin treatment (90 mg/kg) for 28 days...

Osmotic diuresis results from urine loss of large amounts of solutes distributed either in total body water or in the extracellular compartment. Replacement solutions should reflect the volume and monovalent cation (sodium and potassium) content of the fluid lost. Whereas the volume of the solutions used to replace losses that occurred prior to the diagnosis of osmotic diuresis is guided by the clinical picture, the composition of these solutions is predicated on serum sodium concentration and urinary sodium and potassium concentrations at presentation...
